Spring Boot Multipart文件上传产生格式错误的多部分请求

我目前正在运行Spring Boot v1.3.0.BUILD-SNAPSHOT和Spring v4.2.2.BUILD-SNAPSHOT.

如果我尝试执行多文件上传(通过角度)：

myService.upload = function(name,content) {
    var fd = new FormData();
    fd.append('name',name);
    fd.append('file',content);   

    return $http({
      method: 'POST',url: SERVER_BASE_URL + 'upload',data: fd,transformRequest: angular.identity,headers: {
        'Content-Type': 'multipart/form-data'
      }}).then(function(res) {       
        return res.headers('Location');
      },function(reason) {
          throw reason;
      });
};

我收到错误：

我添加了一个多部分解析器bean：

@Bean
public FilterRegistrationBean openEntityManagerFilterRegistrationBean() {
    // Set upload filter
    final MultipartFilter multipartFilter = new MultipartFilter();
    final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(multipartFilter);
    filterRegistrationBean.addInitParameter("multipartResolverBeanName","commonsMultipartResolver");

    return filterRegistrationBean;
}

@Bean
public CommonsMultipartResolver commonsMultipartResolver() {
    final CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setMaxUploadSize(-1);

    return commonsMultipartResolver;
}

但是看来hiddenHttpMethodFilter在我的多部分解析器之前仍然被调用：

[DEBUG] org.eclipse.jetty.servlet.ServletHandler – call filter characterEncodingFilter
[DEBUG] org.eclipse.jetty.servlet.ServletHandler – call filter hiddenHttpMethodFilter
[WARN] org.eclipse.jetty.util.MultiPartInputStreamParser – Badly formatted multipart request

我尝试将@Order(0)添加到我的Bean中,但这没有任何效果.

我还缺少什么？
